To all whom it may concern:

Be it known that we, GEORGE B. DoAN and HART HANsoN, citizens of the United States, and residents of Chicago, Cook county, Illinois, have invented certain new and useful Improvements in Game-Boards, of which the following is a specification.

Our invention relates to game boards, and has articular reference to games of the quasi-educational type.

The objects of the invention are, Erst, to provide amusement for one or more persons,

and, second to, at the same time, train the mind, through the medium of the eye, as to relative or comparative sizes or measure-V ments.

It is a well-known fact that a number of disks or openings of like form and practically the same dimensions, presented to the untrained eye, cause what might be termed an optical illusion, the eye not being able to differentiate readily between them or compare any particular disk or openin with a corresponding disk or opening slig tly re` moved therefrom. Therefore, as above stated, our invention is intended to provide, in connection with an amusement device, training for the eye and mind of those playing the game.

lVith these objects in view, our invention consists, generally, in a device of the class described consisting in aboard or plate, preferably rectangular in shape, composed of cardboard or other suitable material and provided with indentations, depressions or cups, each half of the rectangle presenting cups exactly corresponding, (except as to location) with the cups in the other half, each pair of cups varying kin size from-the other pairs, in combination with disks or counters, each adapted to fit one cup in each half of the board, with means for removing readily said counters after having been placed in the cups.

Our invention will be more readily understood by reference tothe accompanying drawings, forming a part of this specification, andinwhich Figure 1 is a plan view of` a game board embodying our invention Fig. 2 is a transverse vertical section of the same, on the line :1c-:c of Fig. I, showing the counters or disks in place in the cups or indentations; and Figs. 3, 4 and 5 are plan views of the disks which we employ in the carrying out of the invention.

' Referring to the drawings, 2, represents a board containing in one half or section thereof, apertures, c, b, c, d, @,f, g, h, i, of circular outline, varying slightly from each other in diameter, and in its other half or portion, corresponding apertures a', t', c', d', c,f,g,h,i. A board, 3, of the same dimensions as board 2, is secured to the back of board, 2, by suitable means, preferably a strip of binding tape, 4. The board, 3, also contains circular a ertures of uniform size, registering with t e apertures in the board, 2, the purpose of which will appear hereinafter. The board,

3, not only forms a backing fo'r board, 2, .but

affords the bottom of the cups or depresslons for the disks or counters.

5, 6 and 7 represent three of the disks or counters which are of circular outline, and are adapted to fit indentations g, h and 'i respective y.

The manner of employing our invention is as follows :l Two persons are supplied with an equal number of disks, preferably one for each cup or indentation in their half of the board. At a iven signal the opponents endeavor to quiclly fit the disks in their places, the effort of each layer being to properly locate all of the dislis in their proper cups or indentations in the shortest space of time. After the completion of the contest, the disks having been applied to their proper indentations, the pressure of the finger applied to the backs of the disks through the apertures will readily dislodge the same from the indentations.

It will be obvious that the number, combination, size and shape of the cups or indentations and disks or counters may be varied; and that the game may be played by one or more persons on each side. While we prefer to form the cups by cutting out the counters from the board thereby producing the counters and at the same time obtaining their eX- act correspondence with the cups, it is obvious that the indentations or cups may be produced by stampin or embossing, without removing the materia of the boards and that the cups may be defined by beading or throwing up circular ribs from the body of the board. These and other variations within the skill of the constructor we consider are embraced by our invention.

Ve claim: 1. A game board of the class described ,havingtvvo series of circular indentations or cups of similar formation, the individual oups of each series corresponding each With a cup of the other series but varying from each other in size, in combination with counters adapted to be fitted one in each cup, and means for removin the same therefrom, substantially as and or the purpose speoiiied.

2. A game board of the class described, comprising a board having circular apertures or cups of varying sizes therein and a second board adapted to be secured to the back of the iirst, and provided With apertures registering With the cups and aordin` a perforated bottom therefor, and a plura `ty of eiroular counters or disks, each adapted to iit one of said cups, substantially as and for the i GEO.
